This is due to insufficient validation checks within the _register_user() function called by the 'wp_ajax_nopriv_stm_lms_register' AJAX action. This makes it possible for unauthenticated attackers to register a user with administrator-level privileges when MasterStudy LMS Pro is installed and the LMS Forms Editor add-on is enabled.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8},"cwes":["CWE-266"],"references":["https://docs.stylemixthemes.com/masterstudy-lms/changelog-free-version#id-3.3.2","https://plugins.trac.wordpress.org/changeset/3059676/masterstudy-lms-learning-management-system","https://www.wordfence.com/threat-intel/vulnerabilities/id/94736152-b365-4b3a-a786-ed49f7d0fc7a?source=cve","https://docs.stylemixthemes.com/masterstudy-lms/changelog-free-version#id-3.3.2","https://plugins.trac.wordpress.org/changeset/3059676/masterstudy-lms-learning-management-system"],"products":["stylemixthemes:masterstudy_lms"],"source":"nvd","synced_at":"2026-10-19T21:47:51.568503435+00:00"},"epss":{"cve":"CVE-2024-2409","score":0.00834,"percentile":0.57684,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
